Exploring the Dangers of Nitrogen Poisoning and the Design of Underwater Spacesuits

This chapter provides insights into the risks of nitrogen poisoning during rapid ascent underwater and the mechanics of testing and constructing underwater spacesuits. Discussions include the challenges of pressure control in the hands of the suit, the intricacies of maintaining uniform pressure for movement, and the use of blind tests to evaluate astronauts' performance. Further topics cover pressure requirements for spacewalks, the dangers of high oxygen levels, and the use of nitrox gas mixes in diving scenarios for extended dive times and safe decompression.
